It currently only Nostra regulates and corrects IMDB plugin (maybe in the future if anything otherwise, it'll see ...). It is important to be patient and wait for it to Nostra finds time to correct the plugin.

i don't know what happened but seems like the episodes are now in. I just went and check on the series again but somehow the episodes that was not there is there now. I am not sure what happened. Cause I did re-open pvd a few times during when there is problem. Seems like working now.

I just tried importing another TV series from imdb and after import, I need to press the save button (green check button) and the episodes will appear.
